Can anyone solve x plus 4y equals 7 and x plus y equals 4 as a simultaneous equation and show their working?
x+4y = 7 x+y = 4 Subtract the second equation from the first equation: 3y = 3 Divide both sides by 3 in order to find the value of y: y = 1 Substitute the value of y into both original equations in order to find the value of x: Therefore it follows that: x = 3 and y = 1
Can you show me a smart math problem?
Find the exact value of the mathematical symbol pi.
B is the midpoint of A and C If BC equals 3x2 and AC equals 54 find the value of x Show all work to receive credit?
since BC=1/2 AC you take half of 54 then solve the equation. 3x^2=54/2 3x^2=27 x^2=9 x=3
What is the value of x given the equation 5 to the power of 1- 2 x equals 0.25 correct to 3 decimal places Please show working out?
51-2x = 0.25 51 * 5-2x = 0.25 5-2x = 0.05 -2x*ln(5) = ln(0.05) x = ln(0.05)/[-2*ln(5)] = 0.931

Which value of r indicates a stronger correlation r equals 0.834 or r equals -0.925?
Oh, isn't that just lovely? Both values show a strong correlation, but the one closer to 1 or -1 indicates a stronger relationship. So, in this case, r equals 0.834 is slightly stronger than r equals -0.925. Just remember, both values show a beautiful connection between the variables.
